    Enhancing production with Electric Submersible Pumps (ESP) – Challenges and Solutions        JJ Xiao Saudi Aramco   Abstract:   ESP is a mature artificial lift technology having been in existence for at least 80 years. Yet its applications are still engineering intensive, and numerous challenges still remain. Two significant ones topping the list are run life and intervention cost. The run life of ESPs is still far from desirable. This is particularly true for fields with high H2S concentration. Most ESPs today are installed and replaced with workover rigs with jointed pipes. To replace a failed ESP, the waiting time for a workover rig can be long and the workover time and cost can be high, especially for offshore fields. This presentation first provides insights on the leading causes of ESP failures revealed through Dismantle Inspection Failure Analysis (DIFA) of hundreds failed ESPs. It then leads the audience through the research, development, trial tests of new technologies targeting 10-years of ESP run life and 1-day ESP replacement. It shows how subsea technology can be adopted to re-engineer the ESP power delivery system to bring about a whole new level of reliability. To move away from workover rig utilization, a novel rigless cable-deployed ESP system was developed. The presentation also highlights new techniques being developed to address other challenges such as slim well completion. Experience and technologies discussed in this presentation are applicable for operators worldwide. It is evident that when it comes to ESP challenges, operators cannot be passive. It is critical to actively engage and collaborate with service providers to turn challenges into opportunities.     Biography:  Dr. JJ Xiao is a Petroleum Engineering Consultant working in Saudi Aramco’s Advanced Research Center. He is the focus area champion for artificial lift, leading a team of multi-discipline researchers to catalyze the industry, innovate, develop, trial test and commercialize cutting edge artificial lift technologies to improve system reliability, operational efficiency, and to expand system capabilities into ever challenging field applications. Prior to joining Saudi Aramco in 2003, JJ spent 10 years with Amoco and later BP-Amoco, working on multiphase flow, flow assurance and deepwater production engineering. He received both his M.S. and Ph.D. degrees in Petroleum Engineering from the University of Tulsa, Tulsa, OK. JJ has authored 40 technical publications including journal and conference papers. He holds 9 patents and has additional 27 patent applications under processing.

    CO2 in the Subsurface - From EOR to Storage    Gary Teletzke ExxonMobil Upstream Research   Abstract:  The Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA) have issued recent reports suggesting that deployment of carbon dioxide capture and storage (CCS) can significantly reduce the cost of achieving CO2 emission reduction targets.  However, several questions remain: Under what circumstances will large-scale deployment take place? Where and when will this occur? How large a role will CCS play in stabilizing atmospheric concentrations of CO2? I will review the current status of CO2-EOR and geologic storage focusing on subsurface lessons learned and their implications for large-scale CCS.   Our industry has a long history with CO2-EOR that provides a strong experience base for CO2 storage. However, CO2-EOR alone will be insufficient to meet emission reduction targets and storage in deep saline aquifers is also being investigated.Experience from operating CCS projects shows that subsurface storage capacity in saline formations can be limited by dynamic injectability factors. Hundreds of years of CO2 storage capacity is potentially available, even after accounting for dynamic limitations, but the areal distribution of potential storage capacity is widely varied. Geologic and reservoir engineering studies will be essential for identifying storage sites having adequate capacity, containment, and injectivity. Petroleum engineers will play a key role in these studies.     Biography:  Gary Teletzke is Senior Technical Advisor for Enhanced Oil Recovery at ExxonMobil Upstream Research Company. He has led research projects related to gas injection EOR, chemical EOR, and compositional reservoir simulation. He has also led several EOR field studies, integrating laboratory work, reservoir simulation, and pilot testing. For the past ten years, he has provided technical leadership to research efforts on CO2 sequestration. He has published more than 40 technical papers and patents. He has organized numerous SPE conferences over the past two decades and served as Executive Editor of SPEREE from 2015-2017. He was named an SPE Distinguished Member in 2013. He received a BS in chemical engineering from Northwestern University and PhD in chemical engineering from University of Minnesota.
